I'm also thinking that the Navy would not use the Fuze Extenders because of the G-forces on the bombs when the plane is launched from a catapult. The Air Force would not have that problem. Here are couple of photos of Air Force Phantoms with "Daisy Cutter" fuze extenders.

The Daisy Cutters were also used on the 15,000 Lb. BLU-82 which was dropped by Skycrane helicopters and C-130 Aircraft, and the MOAB bomb used two of the fuze extenders.

Note the 2 pictures of the F-4s the bombs have conical fins attached not snake eyes. But with these pictures it would seem that the aircraftspeeed does not have much to do with the fuze extenders use. I would think that by using conical fins the planning would be for the aircraft to drop the ordnance and be out of the frag zone by the time the ordnance detonated. In otherwords not close air support, while snake eyes would allow the aircraft to get closer to the target (more accurate targeting) for release of the ordnance and by retarding the ordnance fall to earth allow the aircraft to remove itself from the frag zone upon ordnance detonation.

Yes from everything I have read, learned and observed "balutes" rertarding devices were developed after "Snake-eyes". IIRC I first started (eyes on not pictures or drawings) seeing balutes on the bombing ranges in the early-mid 1980s, they may have been used earlier,but this is knowledge of when I started to observe them.

I agree with "x" in that I do not remember see balutes in pictures or documents from the VN time period. Your mileage may vary.

The page indicates that only MK82 500 and MK 83 1000 lb low drag General purpose (LDGP) bombs were to be used with the fuze extender on that airframe. Each airframe has its own service approved fuse and ordnance combinations. It seems that my thought of speed (hi speed/low speed) and "G" forces effect on the ordnance with fuxe extenders was incorrect.

Oh well, back to the drawing board. I wish some air frame drivers would chime in, to help us grounded folks out.
